DETAILED DESCRIPTION

[0069] Embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Embodiments of the present invention are described in detail below.

[0070] The air conditioner in this application performs a refrigeration cycle of the air conditioner by using a compressor, a condenser, an expansion valve and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion and evaporation, and supplies refrigerant to the air that has been conditioned and heat-exchanged.

[0071] The compressor compresses the refrigerant gas in a high temperature and high pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0072] The expansion valve expands the high-temperature and high-pressure liquid refrigerant condensed in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a refrigeration effect by utilizing the latent heat of evaporation of the refrigerant to exchange heat with the material to be cooled. In the entire cycle, the air conditioner can adjust the temperature of the indoor space.

[0073] The outdoor unit of the air conditioner refers to a portion of a refrigeration cycle including a compressor and an outdoor heat exchanger, the indoor unit of the air conditioner includes an indoor heat exchanger, and an expansion valve may be provided in the indoor unit or the outdoor unit.

[0074] The indoor heat exchanger and the outdoor heat exchanger function as a condenser or an evaporator. When the indoor heat exchanger functions as a condenser, the air conditioner functions as a heater in a heating mode, and when the indoor heat exchanger functions as an evaporator, the air conditioner functions as a cooler in a cooling mode.

[0075] Reference below Figure 1-Figure 4 The air conditioner 10 according to the embodiment of the present invention is described, including an air conditioner outdoor unit 100, an air conditioner indoor unit 200, a balcony clothes dryer 300 and a controller.

[0076] Specifically, the air conditioner outdoor unit 100 is placed outdoors, and the air conditioner outdoor unit 100 includes: an outdoor heat exchanger; the air conditioner indoor unit 200 is placed indoors, and the air conditioner indoor unit 200 includes: an indoor heat exchanger, and the indoor heat exchanger is connected to the outdoor heat exchanger; the balcony dryer 300 is placed on the balcony, and the balcony dryer 300 includes: a balcony dehumidifier 311 and a balcony dryer 312, the balcony dehumidifier 311 is connected to the outdoor heat exchanger, and the balcony dryer 312 includes: a drying heat exchanger 313, a drying fan, a first temperature sensor and a second temperature sensor, the drying fan is arranged on one side of the drying heat exchanger 313, the drying heat exchanger 313 is connected to the outdoor heat exchanger, the first temperature sensor is used to detect the temperature of the drying heat exchanger 313, and the second temperature sensor is used to detect the ambient temperature around the balcony dryer 312, and the drying heat exchanger 313 is provided with a first short-circuit control valve 3132.

[0077] The controller is configured to:

[0078] Determine the heating / balcony drying mode of the air conditioner 10 and the preset gear position of the drying fan;

[0079] Controlling the first short-circuit control valve 3132 to be adjusted to an initial opening;

[0080] Determine whether the temperature T1 of the first temperature sensor is higher than the first preset temperature value T 设1 :

[0081] At T1 and T 设1 Satisfy the relationship: T1>T 设1 When the drying fan is controlled to run at low speed;

[0082] Determine whether the temperature T2 of the second temperature sensor is higher than the second preset temperature value T 设2 :

[0083] At T2 and T 设2 Satisfy the relationship: T2≤T 设2 When the drying fan is controlled to run at the preset gear, T 设2 >T 设1 .

[0084] It is understandable that before the air conditioner 10 runs the balcony dryer 300 to perform the drying function, it is necessary to first determine the operating status of the air conditioner 10 and forcibly control the first short-circuit control valve 3132 to be adjusted to the initial opening to avoid the operation of the air conditioner 10 being affected by the opening of the first short-circuit control valve 3132, which causes the drying effect to fail to meet the predetermined requirements or the operating effect to be too good.

[0085] After the first short-circuit control valve 3132 is adjusted to the initial opening, the first temperature sensor is started and detects the temperature of the drying heat exchanger 313. When the temperature detected by the first temperature sensor is greater than the first preset temperature, it means that the heat provided by the drying heat exchanger 313 can meet the demand for drying clothes. Therefore, the drying fan is controlled to run at a low gear.

[0086] Then, the second temperature sensor is determined and the ambient temperature around the balcony dryer 312 is detected. When the temperature detected by the second temperature sensor is not greater than the second preset temperature, it is suitable to indicate that the balcony dryer 312 can achieve a higher-level drying effect, so the drying fan is controlled to operate according to the preset gear.

[0087] According to the air conditioner 10 of the embodiment of the present invention, by configuring the controller to control and adjust the operating gear of the drying fan through the first temperature sensor and the second temperature sensor, the operating gear of the drying fan can be adjusted according to the use of the drying heat exchanger 313 and the function of the balcony dehumidifier 311, so that the drying function of the air conditioner 10 can be adjusted according to the operating conditions of the air conditioner 10, which will not only improve the effect of the drying function of the air conditioner 10, but also save resources, reduce drying costs, and improve drying efficiency.

[0088] In some embodiments, the controller is further configured to:

[0089] Determine whether the temperature T1 of the first temperature sensor is higher than the first preset temperature value T 设1 , specifically:

[0090] At T1 and T 设1 Satisfy the relationship: T1≤T 设1 When the first short-circuit control valve 3132 is controlled to reduce its opening degree, until T1 and T 设1 Satisfy the relationship: T1>T 设1 .

[0091] That is to say, when the temperature T1 of the first temperature sensor is not greater than the first preset temperature value, it means that the drying heat exchanger 313 cannot provide sufficient heat to constitute the drying function. Therefore, the opening of the first short-circuit control valve 3132 is reduced to improve the performance of the drying heat exchanger 313. When the drying heat exchanger 313 has a high performance to meet the drying function of the air conditioner 10, the opening of the first short-circuit control valve 3132 is stopped from being reduced.

[0092] In some embodiments, the controller is further configured to:

[0093] Determine whether the temperature T2 of the second temperature sensor is higher than the second preset temperature value T 设2 , specifically:

[0094] At T2 and T 设2 Satisfies the relationship: T2>T 设2 When the drying fan is controlled to run at a low gear, the first short-circuit control valve 3132 increases its opening until T2 and T 设2 Satisfy the relationship: T2≤T 设2 .

[0095] In this way, when the temperature T2 of the second temperature sensor is greater than the second preset temperature value, the balcony dryer 312 has too high drying performance, resulting in a waste of resources. Therefore, the opening of the first short-circuit control valve 3132 is controlled to increase, and the drying performance of the balcony dryer 312 is reduced until the balcony dryer 312 can reasonably utilize the heat of the air conditioner 10 when running the drying function, and then the opening of the first short-circuit control valve 3132 is stopped from increasing.

[0096] In some embodiments, the controller is specifically configured to:

[0097] Determine whether the temperature T2 of the second temperature sensor is higher than the second preset temperature value T 设2 Previously, the controller was configured as:

[0098] Determine whether the temperature T2 of the second temperature sensor is higher than the third preset temperature value T 设3 :

[0099] At T2 and T 设3 Satisfies the relationship: T2>T 设3 When the drying fan is turned on, it controls the drying fan to run according to the preset gear.

[0100] It can be understood that when controlling the air conditioner 10 to run the drying function, the temperature detected by the second temperature sensor can be checked to see if it is greater than the third preset temperature value. When it is detected that the temperature of the second temperature sensor is greater than the third preset temperature value, it is suitable for indicating that there is a high heat around the balcony dryer 312 for drying clothes. Therefore, the drying fan is controlled to operate according to the preset gear, so that the air conditioner 10 has a higher drying efficiency.

[0101] In some embodiments, the controller is specifically configured to:

[0102] Determine whether the temperature T2 of the second temperature sensor is higher than the third preset temperature value T 设3 , specifically:

[0103] At T2 and T 设3 Satisfy the relationship: T2≤T 设3 When the drying fan is controlled to run at a low gear, the first short-circuit control valve 3132 is opened less until T2 and T 设3 Satisfies the relationship: T2>T 设3 , where T 设1 ≤T设3 <T 设2 .

[0104] In this way, since the temperature T2 detected by the second temperature sensor is less than the third preset temperature value, it is suitable to explain that the temperature of the environment where the balcony dryer 312 is located is relatively low, and therefore, the clothes drying effect of the balcony dryer 312 is relatively poor, so the drying fan is controlled to run at a low gear so that the drying heat exchanger 313 can provide enough heat to form the clothes drying effect of the air conditioner 10. At the same time, the opening of the first short-circuit control valve 3132 is reduced to increase the heat that can be provided by the drying heat exchanger 313, thereby improving the clothes drying effect of the air conditioner 10.

[0105] In some embodiments, the balcony dehumidifier 311 includes: a dehumidification heat exchanger 314, a dehumidification fan and a third temperature sensor, the dehumidification fan is arranged on one side of the dehumidification heat exchanger 314, the dehumidification heat exchanger 314 is connected to the outdoor heat exchanger, the third temperature sensor is used to detect the temperature of the dehumidification heat exchanger 314, and the dehumidification heat exchanger 314 is provided with a second short-circuit control valve 3142;

[0106] The controller is also configured to:

[0107] Determine the cooling / balcony dehumidification mode of the air conditioner 10 and the preset gear position of the dehumidification fan;

[0108] Control the second short-circuit control valve 3142 to adjust to an initial opening;

[0109] Determine whether the temperature T3 of the third temperature sensor is lower than the fourth preset temperature value T 设4 :

[0110] At T3 and T 设4 Satisfy the relationship: T3<T 设4 When the dehumidification fan is controlled to run at low speed;

[0111] Determine whether the temperature T3 of the third temperature sensor is lower than the fifth preset temperature value T 设5 :

[0112] At T3 and T 设5 Satisfy the relationship: T3≥T 设5 When the dehumidification fan is controlled to run at the preset gear, T 设5 <T 设4 <T 设1 .

[0113] It should be noted that the balcony dryer 312 can not only dry clothes by providing heat, but also dry clothes by reducing the humidity of the clothes.

[0114] It is understandable that before the air conditioner 10 runs the balcony dryer 300 to perform the dehumidification and drying function, it is necessary to first determine the operating status of the air conditioner 10 and forcibly control the second short-circuit control valve 3142 to be adjusted to the initial opening to avoid the drying effect failing to meet the predetermined requirements or the operating effect being too good due to the opening of the second short-circuit control valve 3142, which affects the operation of the air conditioner 10.

[0115] After the second short-circuit control valve 3142 is adjusted to the initial opening, the third temperature sensor is started and detects the temperature of the dehumidification heat exchanger 314. When the temperature detected by the third temperature sensor is lower than the fourth preset temperature, it indicates that the dehumidification heat exchanger can condense the moisture in the environment well. Therefore, the dehumidification fan is controlled to run at a low gear.

[0116] Then, it is determined whether the temperature detected by the third temperature sensor is lower than the fifth preset temperature. When the temperature detected by the third temperature sensor is greater than or equal to the fifth preset temperature, it means that the dehumidification heat exchanger 314 can absorb heat well. Therefore, the dehumidification fan is controlled to operate according to the preset gear to improve the dehumidification and drying efficiency.

[0117] In some embodiments, the controller is further configured to:

[0118] Determine whether the temperature T3 of the third temperature sensor is lower than the fourth preset temperature value T 设4 , specifically:

[0119] At T3 and T 设4 Satisfy the relationship: T3≥T 设4 When the second short-circuit control valve 3142 is controlled to reduce the opening degree, until T3 and T 设4 Satisfy the relationship: T3<T 设4 .

[0120] It can be understood that when the temperature detected by the third temperature sensor is greater than the fourth preset temperature value, it means that the dehumidification and drying function provided by the dehumidification heat exchanger 314 is not sufficient to meet the needs of drying clothes. Therefore, the opening of the second short-circuit control valve 3142 is reduced to enhance the dehumidification and drying function of the dehumidification heat exchanger 314 until the temperature detected by the third temperature sensor is lower than the fourth preset temperature value.

[0121] In some embodiments, the controller is further configured to:

[0122] Determine whether the temperature T3 of the third temperature sensor is lower than the fifth preset temperature value T 设5 , specifically:

[0123] At T3 and T 设5 Satisfy the relationship: T3<T 设5 When the dehumidification fan is controlled to run at low speed, the second short-circuit control valve 3142 increases its opening until T3 and T设5 Satisfy the relationship: T3≥T 设5 .

[0124] That is to say, when the temperature detected by the third temperature sensor is lower than the fifth preset temperature value, it indicates that the dehumidification and clothes drying function of the dehumidification heat exchanger 314 is too strong. Therefore, it is necessary to open the second short-circuit control valve 3142 to reduce the dehumidification and clothes drying function of the dehumidification heat exchanger 314 and avoid wasting resources.

[0125] In some embodiments, the controller is specifically configured to:

[0126] Determine the preset gear position of the air conditioner 10 in the cooling / balcony dehumidification mode and the dehumidification fan, specifically:

[0127] The preset gear is mid-range or high-range;

[0128] Determine whether the temperature T3 of the third temperature sensor is lower than the fifth preset temperature value T 设5 Previously, the controller was configured as:

[0129] Determine whether the temperature T3 of the third temperature sensor is lower than the sixth preset temperature value T 设6 :

[0130] At T3 and T 设6 Satisfy the relationship: T3<T 设6 When the dehumidification fan is controlled to run at the middle gear, T 设5 <T 设6 <T 设4 .

[0131] In this way, when it is detected that the temperature of the third temperature sensor is less than the sixth preset temperature value, it means that the dehumidification heat exchanger 314 can provide a higher dehumidification and drying function, so the gear of the dehumidification fan can be increased to improve the drying efficiency.

[0132] In some embodiments, the controller is specifically configured to:

[0133] Determine whether the temperature T3 of the third temperature sensor is lower than the sixth preset temperature value T 设6 , specifically:

[0134] At T3 and T 设6 Satisfy the relationship: T3≥T 设6 When T3 and T 设6 Satisfy the relationship: T3<T 设6It is understandable that when the gear of the dehumidification fan is increased, the third temperature sensor needs to be used to perform real-time detection of the dehumidification heat exchanger 314. When the temperature detected by the third temperature sensor is greater than the sixth preset temperature value, it means that the dehumidification and drying function provided by the dehumidification heat exchanger 314 is insufficient to perform the dehumidification and drying function of the preset gear. Therefore, it is necessary to reduce the opening of the second short-circuit control valve 3142 to increase the dehumidification and drying function of the dehumidification heat exchanger 314 until the dehumidification and drying function provided by the dehumidification heat exchanger 314 is able to perform the dehumidification and drying function of the preset gear.

[0135] According to the control method of the air conditioner 10 of the embodiment of the present invention, the air conditioner 10 includes: an air conditioner outdoor unit 100, an air conditioner indoor unit 200 and a balcony clothes dryer 300, the balcony clothes dryer 300 includes: a balcony dehumidifier 311 and a balcony drying machine 312, the balcony drying machine 312 includes: a drying heat exchanger 313, a drying fan, a first temperature sensor and a second temperature sensor, the first temperature sensor is used to detect the temperature of the drying heat exchanger 313, and the second temperature sensor is used to detect the ambient temperature around the balcony drying machine 312;

[0136] The control method comprises the following steps:

[0137] Determine the heating / balcony drying mode of the air conditioner 10 and the preset gear position of the drying fan;

[0138] The first short-circuit control valve 3132 is adjusted to an initial opening;

[0142] At T2 and T 设2 Satisfy the relationship: T2≤T 设2 When the drying fan runs at the preset gear, T 设2 >T 设1 .

[0143] According to the control method of the air conditioner 10 in the embodiment of the present invention, by configuring the controller to control and adjust the operating gear of the drying fan through the first temperature sensor and the second temperature sensor, the operating gear of the drying fan can be adjusted according to the use of the drying heat exchanger 313 and the function of the balcony dehumidifier 311, so that the drying function of the air conditioner 10 can be adjusted according to the operating conditions of the air conditioner 10, which will not only improve the effect of the drying function of the air conditioner 10, but also save resources, reduce the cost of drying clothes, and improve the efficiency of drying clothes.

[0144] According to the air conditioner 10 of the embodiment of the present invention, specifically, the air conditioner outdoor unit 100 is placed outdoors; the air conditioner indoor unit 200 is placed indoors, and the air conditioner indoor unit 200 is connected to the air conditioner outdoor unit 100; and, the balcony dryer 300 is placed on the balcony, and the balcony dryer 300 is connected to the air conditioner outdoor unit 100.

[0145] It can be understood that during the construction of the air conditioner 10, the air conditioner outdoor unit 100 is configured outdoors, the air conditioner indoor unit 200 is configured indoors, and the balcony dryer 300 is configured on the balcony. The air conditioner outdoor unit 100 is connected to the air conditioner outdoor unit 100, and the refrigerant is suitable for flowing between the air conditioner outdoor unit 100 and the air conditioner indoor unit 200. While entering the air conditioner outdoor unit 100, the refrigerant can also enter the balcony dryer 300 to dry the clothes placed on the balcony.

[0146] According to the air conditioner 10 of the embodiment of the present invention, a balcony dryer 300 is provided on the balcony. The balcony dryer 300 can utilize the heat in the refrigerant flowing between the air conditioner indoor unit 200 and the air conditioner outdoor unit 100 to dry the clothes placed on the balcony.

[0147] In some embodiments, Figure 1 As shown, the balcony clothes dryer 300 includes: a clothes dryer heat exchanger 310 and a clothes dryer fan 320. The clothes dryer heat exchanger 310 is connected to the air conditioner outdoor unit 100, and the clothes dryer fan 320 is arranged on one side of the clothes dryer heat exchanger 310. In this way, since the balcony clothes dryer 300 includes the clothes dryer heat exchanger 310 and the clothes dryer fan 320, the clothes dryer heat exchanger 310 is suitable for exchanging heat with the refrigerant, so that heat can be dissipated from the clothes dryer heat exchanger 310 to improve the ambient temperature of the balcony, and the clothes dryer fan 320 is suitable for allowing the heat dissipated by the clothes dryer heat exchanger 310 to act on the balcony environment more quickly to improve the drying efficiency of the balcony.

[0148] In some embodiments, Figure 1As shown, the balcony clothes dryer 300 is at least two and includes: a balcony dehumidifier 311 and a balcony drying machine 312, and the balcony dehumidifier 311 and the balcony drying machine 312 are respectively connected to the air conditioner outdoor unit 100. It can be understood that the balcony clothes dryer 300 includes two modules, namely the balcony dehumidifier 311 and the balcony drying machine 312, the balcony dehumidifier 311 is suitable for reducing the humidity in the balcony space, and the balcony clothes dryer 300 is suitable for increasing the temperature in the balcony space. By arranging the balcony dehumidifier 311 and the balcony drying machine 312 on the balcony, the balcony dehumidifier 311 and the balcony drying machine 312 can adopt different methods to dry the clothes placed on the balcony according to different environmental requirements, so that the balcony clothes dryer 300 has higher applicability to meet the drying needs.

[0149] In some embodiments, Figure 1 As shown, the balcony dryer 312 is connected in series with the air conditioner outdoor unit 100, the balcony dehumidifier 311 is connected in series with the air conditioner outdoor unit 100, and the balcony dehumidifier 311 is connected with the air conditioner indoor unit 200. It should be noted that the balcony dryer 312 is suitable for releasing heat, and the balcony dehumidifier 311 is suitable for condensing the moisture in the balcony, so the balcony dehumidifier 311 is suitable for absorbing heat. In this way, the balcony dryer 312 is connected to the air conditioner outdoor unit 100, and the balcony dehumidifier 311 is connected to the air conditioner outdoor unit 100, so that the heat in the refrigerant of the air conditioner 10 can be more reliably utilized during use, so that the use of the balcony dryer 300 is more reliable, the drying effect of the clothes is higher, and the use cost of the balcony dryer 300 is lower.

[0150] In some embodiments, Figure 1 As shown, the air conditioner outdoor unit 100 includes: a compressor 110, a four-way valve 120 and an outdoor heat exchanger 130, the air conditioner indoor unit 200 includes: an indoor heat exchanger 210, and the balcony dryer 312 includes: a drying heat exchanger 313, both ends of the compressor 110 are connected to the four-way valve 120, the four-way valve 120 is connected to the drying heat exchanger 313, the drying heat exchanger 313 is connected in series with the outdoor heat exchanger 130, the outdoor heat exchanger 130 is connected in series with the indoor heat exchanger 210, and the indoor heat exchanger 210 is connected to the four-way valve 120.

[0151] It can be understood that the compressor 110 is suitable for driving the circulation of refrigerant, driving the refrigerant into the air conditioner indoor unit 200 for heat exchange, and the drying heat exchanger 313 is arranged in series with the outdoor heat exchanger 130, so that the refrigerant that enters the outdoor heat exchanger 130 for heat can enter the drying heat exchanger 313 for heat release, so that the heat exchanged in the indoor environment when the air conditioner 10 is in cooling mode can be utilized, thereby improving the utilization efficiency of the air conditioner 10.

[0152] In some embodiments, Figure 1 As shown, the balcony dehumidifier 311 includes: a dehumidification heat exchanger 314, the dehumidification heat exchanger 314 is connected in series with the outdoor heat exchanger 130, the dehumidification heat exchanger 314 is connected in series with the indoor heat exchanger 210, or the dehumidification heat exchanger 314 is connected in parallel with the indoor heat exchanger 210.

[0153] It can be understood that the dehumidification heat exchanger 314 is suitable for being arranged between the outdoor heat exchanger 130 and the indoor heat exchanger 210, so that the refrigerant flowing out from the outdoor heat exchanger 130 or the indoor heat exchanger 210 can flow to the dehumidification heat exchanger 314 to absorb heat, so that the moisture in the air can condense on the dehumidification heat exchanger 314, thereby forming the balcony's drying performance.

[0154] In some embodiments, Figure 1 As shown, the air conditioner outdoor unit 100 further includes: an outdoor fan 140, which is disposed on one side of the outdoor heat exchanger 130; the air conditioner indoor unit 200 further includes: an indoor fan 220, which is disposed on one side of the indoor heat exchanger 210; the balcony dryer 312 further includes: a drying fan 3131, which is disposed on one side of the drying heat exchanger 313; the balcony dehumidifier 311 further includes: a dehumidifying fan 3141, which is disposed on one side of the dehumidifying heat exchanger 314. It can be understood that the outdoor fan 140 is suitable for improving the outdoor heat exchange effect of the outdoor heat exchanger 130, so that the heat exchange effect of the refrigerant on the outdoor heat exchanger 130 is improved. Similarly, the indoor fan 220 is suitable for improving the indoor heat exchange effect of the indoor heat exchanger 210, the drying fan 3131 is suitable for improving the drying heat exchange effect of the drying heat exchanger 313, and the dehumidification fan 3141 is suitable for improving the dehumidification heat exchange effect of the dehumidification heat exchanger 314. In this way, the performance of the air conditioner 10 is improved.

[0155] In some embodiments, Figure 1As shown, the drying heat exchanger 313 is provided with a first short-circuit control valve 3132; and / or the dehumidification heat exchanger 314 is provided with a second short-circuit control valve 3142; and / or the indoor heat exchanger 210 is provided with a third short-circuit control valve 211. It should be noted that when the short-circuit control valve is opened, the refrigerant is suitable for flowing through the short-circuit control valve, and when the short-circuit control valve is closed, the refrigerant is suitable for stopping flowing from the short-circuit control valve and flowing from the corresponding heat exchanger. That is, when the first short-circuit control valve 3132 is opened, the refrigerant is suitable for flowing from the first short-circuit control valve 3132, and when the first short-circuit control valve 3132 is closed, the refrigerant is suitable for flowing from the drying heat exchanger 313; when the second short-circuit control valve 3142 is opened, the refrigerant is suitable for flowing from the second short-circuit control valve 3142, and when the second short-circuit control valve 3142 is closed, the refrigerant is suitable for flowing from the dehumidification heat exchanger 314; when the third short-circuit control valve 211 is opened, the refrigerant is suitable for flowing from the third short-circuit control valve 211, and when the third short-circuit control valve 211 is closed, the refrigerant is suitable for flowing from the indoor heat exchanger 210. In this way, by providing a short-circuit control valve for the corresponding heat exchanger, the circulation of the refrigerant can be adjusted according to the use of the air conditioner 10, the operating cost can be reduced, and the use performance of the corresponding structure can be improved.

[0156] In some embodiments, Figure 1 As shown, the air conditioner outdoor unit 100 further includes: a first filter 150, a throttling element 160 and a second filter 170, the first filter 150 is connected in series with the outdoor heat exchanger 130, the throttling element 160 is connected in series between the first filter 150 and the second filter 170, and the second filter 170 is connected in series with the dehumidification heat exchanger 314. It can be understood that the first filter 150 and the second filter 170 are suitable for filtering the refrigerant, so as to filter out impurities and moisture in the refrigerant, so that the refrigerant returned to the compressor 110 is purer, so as to facilitate the subsequent recycling of the refrigerant, and the first filter 150 and the second filter 170 are arranged at both ends of the throttling element 160, so as to prevent impurities and the like from entering the throttling element 160 and affecting it, so that the throttling element 160 has a higher performance.

[0157] In some embodiments, Figure 1As shown, the air conditioner outdoor unit 100 also includes: an air intake temperature sensing package 180, a low pressure sensor 190, a low pressure switch 1100 and a gas-liquid separator 1110, and the air intake temperature sensing package 180, the low pressure sensor 190, the low pressure switch 1100 and the gas-liquid separator 1110 are connected in series between the four-way valve 120 and the air inlet of the compressor 110; and / or the air conditioner outdoor unit 100 also includes: a high pressure switch, a high pressure sensor 1130 and an exhaust temperature sensing package 1140, and the high pressure switch, the high pressure sensor 1130 and the exhaust temperature sensing package 1140 are connected in series between the exhaust port of the compressor 110 and the four-way valve 120.

[0158] It can be understood that the air intake temperature sensing package 180, the low pressure sensor 190, the low pressure switch 1100 and the gas-liquid separator 1110 are suitable for being constructed in the path where the refrigerant of the air conditioner 10 circulates, and the high pressure switch, the high pressure sensor 1130 and the exhaust temperature sensing package 1140 are arranged in the path where the refrigerant of the air conditioner 10 circulates. In this way, the above-mentioned structure is correspondingly arranged in the path where the refrigerant circulates in the air conditioner 10 to detect and sense the refrigerant, so that the refrigerant operation or flow path of the air conditioner 10 can be adjusted according to the situation of the refrigerant, so that the air conditioner 10 has higher performance and can drive the operation of the balcony dryer 300 at a higher level.

[0159] In some embodiments, Figure 1 As shown, a sterilization module 3121 and / or a mite removal module 3122 are provided in the balcony dryer 312. Thus, by providing the sterilization module 3121 and the mite removal module 3122 in the balcony dryer 312, the clothes placed on the balcony can be sterilized and mite removed, so that the balcony dryer 312 can dry the clothes and make them cleaner and more hygienic.

[0160] In some embodiments, Figure 1 As shown, the air conditioner outdoor unit 100 includes: a casing 1150, an outdoor heat exchanger 130 and an outdoor fan 140. The outdoor heat exchanger 130 and the outdoor fan 140 are arranged in the casing 1150, and the outdoor fan 140 is arranged on one side of the outdoor heat exchanger 130. A front air outlet is arranged on the front side of the casing 1150, and a rear air outlet is arranged on the rear side of the casing 1150 to transport hot air to the balcony when the outdoor fan 140 reverses.

[0161] In this way, by providing a front air outlet on the front side of the casing 1150 and a rear air outlet on the rear side, when used in the above-mentioned situation, the outdoor fan 140 can improve the performance of the outdoor heat exchanger 130, and because the rear air outlet is provided on the rear side of the casing 1150, the heat exchanged by the outdoor heat exchanger 130 can be applied to the balcony through the rear air outlet, so that the balcony can be heated by utilizing the heat dissipated by the outdoor heat exchanger 130, thereby improving the drying effect of the air conditioner 10.

[0162] In the control method of the air conditioner 10 of the embodiment of the present invention, the logic diagram of the <Cooling / Balcony Drying> and <Low Gear> buttons shows that at this time, the first short-circuit solenoid valve moves from the maximum opening to the initial opening of drying (the initial opening is relatively small), and the high-temperature refrigerant from the compressor 110 directly enters the drying heat exchanger 313. When the first temperature sensor of the balcony dryer 312 detects that the temperature of the drying heat exchanger 313 is higher than 30°C, the drying fan is powered on and runs at a low wind speed; then it is determined whether the temperature of the second temperature sensor on the drying heat exchanger 313 is higher than 30°C. If it is higher than 30°C, the fan continues to run at a low wind speed to accelerate the air flow and temperature uniformity in the space. If it is lower than 30°C, the opening of the first short-circuit solenoid valve is reduced, and more refrigerant flows into the drying heat exchanger 313 until the temperature of the second temperature sensor is higher than 30°C; then it is determined whether the temperature of the second temperature sensor is higher than 40°C. If it is higher than 40°C, the opening of the first short-circuit solenoid valve is increased until the temperature of the second temperature sensor is lower than 40°C. In the balcony drying mode, when the ambient humidity is low, the clothes can be dried using only the drying module.

[0163] As shown in the logic diagram of pressing the <Cooling / Balcony Drying> and <Mid-Gear> buttons, at this time, the first short-circuit solenoid valve moves from the maximum opening to the initial opening of drying (the initial opening is relatively small), and the high-temperature refrigerant coming out of the compressor 110 directly enters the drying heat exchanger 313. When the first temperature sensor of the balcony dryer 312 detects that the temperature of the drying heat exchanger 313 is higher than 30°C, the drying fan is powered on and runs at a low wind speed; then it is determined whether the temperature of the second temperature sensor on the drying heat exchanger 313 is higher than 40°C. If it is higher than 40°C, the fan is upgraded to medium-speed operation to accelerate the air flow and temperature uniformity in the space. If it is lower than 40°C, the opening of the first short-circuit solenoid valve is reduced, and more refrigerant flows into the drying heat exchanger 313 until the temperature of the second temperature sensor is higher than 40°C; then it is determined whether the temperature of the second temperature sensor is higher than 50°C. If it is higher than 50°C, the opening of the first short-circuit solenoid valve is increased until the temperature of the second temperature sensor is lower than 50°C.

[0164] As shown in the logic diagram of pressing the <Cooling / Balcony Drying> and <High> buttons, at this time, the first short-circuit solenoid valve moves from the maximum opening to the initial opening of drying (the initial opening is relatively small), and the high-temperature refrigerant from the compressor 110 directly enters the drying heat exchanger 313. When the first temperature sensor of the balcony dryer 312 detects that the temperature of the drying heat exchanger 313 is higher than 30°C, the drying fan is powered on and runs at a low wind speed; then it is determined whether the temperature of the second temperature sensor on the drying heat exchanger 313 is higher than 50°C. If it is higher than 50°C, the fan is upgraded to a high wind speed to speed up the space air conditioning. Airflow and temperature uniformity, if it is lower than 50℃, the opening of the first short-circuit solenoid valve will be reduced, and more refrigerant will flow into the drying heat exchanger 313 until the temperature of the second temperature sensor is higher than 50℃; then it is determined whether the temperature of the second temperature sensor is higher than 55℃. If it is higher than 55℃, the opening of the first short-circuit solenoid valve will be increased until the temperature of the second temperature sensor is lower than 55℃. If the ambient temperature sensor is above 55℃ for more than 3 minutes, the short-circuit solenoid valve will be opened to the maximum to completely short-circuit the drying heat exchanger 313, so that the temperature of the ambient temperature sensor drops below 55℃. In the balcony drying mode, when the ambient humidity is low, the clothes can be dried using only the drying module.

[0165] High temperature protection of the drying heat exchanger 313: when the balcony drying machine 312 runs continuously for 12 minutes or more, it is tested once every 15 seconds. If the temperature detected by the temperature sensor is between 60°C and 63°C for three consecutive times, the first short-circuit solenoid valve is prohibited from closing the valve; it is tested once every 15 seconds. If the temperature detected by the temperature sensor is higher than 65°C for three consecutive times, the first short-circuit solenoid valve opens at a speed of 1 step per second. After running for 3 minutes at this valve opening speed, it is regularly determined whether the temperature detected by the temperature sensor is higher than 65°C. When the temperature detected by the temperature sensor is between 55°C and 60°C, the first short-circuit solenoid valve maintains the current opening unchanged. The conditions for exiting the protection are: ① If the opening of the first short-circuit solenoid valve is not opened to the maximum and the temperature of the temperature sensor is lower than 60°C, the high temperature protection of the balcony drying module is released; ② If the opening of the first short-circuit solenoid valve is opened to the maximum, 3 minutes after the opening of the short-circuit solenoid valve is opened to the maximum and the compressor 110 is shut down, and the temperature of the temperature sensor is lower than 60°C, the high temperature protection is released.

[0166] As shown in the remote control of the clothes drying balcony air conditioner, after pressing the <room cooling> button, the user presses the <cooling / balcony dehumidification> and <high-end> buttons, taking the logic diagram when pressing the <cooling / balcony dehumidification> and <high-end> buttons as an example, at this time, the short-circuit solenoid valve of the balcony dehumidification module will move from the maximum opening state to the initial dehumidification opening state. At this time, the refrigerant liquid condensed by the outdoor unit enters the dehumidification heat exchanger 314 through the throttling element for evaporation and heat absorption, so that the temperature of the dehumidification heat exchanger 314 is reduced to achieve dehumidification. When the temperature detected by the third temperature sensor of the dehumidification heat exchanger 314 is lower than 20°C, the dehumidification fan is powered on and runs at a low wind speed. If the temperature detected by the third temperature sensor of the dehumidification heat exchanger 314 is higher than 20°C, the opening of the short-circuit solenoid valve is reduced, and the refrigerant flowing into the dehumidification heat exchanger 314 is increased until the temperature detected by the third temperature sensor of the dehumidification heat exchanger 314 is lower than 20°C, and the dehumidification fan is powered on and runs at a low wind speed. Then the temperature of the third temperature sensor is detected to be lower than 15°C. If it is lower than 15°C, the dehumidification fan is powered on and runs at a low wind speed. ℃, the dehumidification fan is upgraded to medium wind operation. If it is higher than 15℃, the opening of the short-circuit solenoid valve continues to decrease until the temperature detected by the third temperature sensor is lower than 15℃, and the fan is upgraded to medium wind operation; then the temperature of the third temperature sensor is detected to be lower than 10℃. If it is lower than 10℃, the dehumidification fan is upgraded to high wind operation. If it is higher than 10℃, the opening of the short-circuit solenoid valve continues to decrease until the temperature detected by the third temperature sensor is lower than 10℃, and the dehumidification fan is upgraded to high wind operation; then the temperature of the third temperature sensor is detected to be lower than 5℃. If it is higher than 5℃, the dehumidification fan continues to run at high wind. If it is lower than 5℃, the opening of the short-circuit solenoid valve increases, and the amount of refrigerant flowing into the dehumidification heat exchanger 314 decreases until the temperature detected by the third temperature sensor is higher than 5℃; finally, the system enters a closed-loop feedback, and the temperature detected by the third temperature sensor will be controlled between 5℃ and 10℃. Operation in this temperature range avoids the freezing of the evaporator during the dehumidification process, and the condensed water is discharged from the water receiving tray and the drain pipe at the bottom of the dehumidification heat exchanger 314.

[0167] Balcony dehumidification module anti-freezing protection control logic: When the dehumidification module runs continuously for 12 minutes or more, it is tested once every 15 seconds. If the temperature detected by the third temperature sensor is between 3°C and 5°C for three consecutive times, the short-circuit solenoid valve is prohibited from closing the valve; it is tested once every 15 seconds. If the temperature detected by the third temperature sensor is lower than 1°C for three consecutive times, the short-circuit solenoid valve opens at a speed of 1 step per second. After running for 3 minutes at this valve opening speed, it is regularly determined whether the temperature detected by the third temperature sensor is higher than 5°C. When the temperature detected by the third temperature sensor is between 5°C and 8°C, the short-circuit solenoid valve maintains the current opening unchanged. The conditions for exiting the protection are: ① If the opening of the short-circuit solenoid valve makes the temperature of the third temperature sensor higher than 8°C when it is not opened to the maximum, the balcony dehumidification module anti-freezing protection is released; ② If the opening of the short-circuit solenoid valve is opened to the maximum, the compressor 110 is shut down for protection. After the opening of the short-circuit solenoid valve is opened to the maximum and the compressor 110 is shut down for 3 minutes, and the temperature of the third temperature sensor is higher than 8°C, the anti-freezing protection is released.

[0168] After pressing <Room Cooling>, the user presses the <Cooling / Balcony Dehumidification> and <Mid-Gear> buttons, the short-circuit solenoid valve of the balcony dehumidification module will move from the maximum opening state to the initial dehumidification opening state. At this time, the refrigerant liquid condensed by the outdoor unit enters the dehumidification heat exchanger 314 through the throttling of the throttling element for evaporation and heat absorption, so that the temperature of the dehumidification heat exchanger 314 is reduced to realize the dehumidification function. When the temperature detected by the third temperature sensor of the dehumidification heat exchanger 314 is lower than 20°C, the dehumidification fan is powered on and operates at low wind speed. If the temperature detected by the third temperature sensor of the dehumidification heat exchanger 314 is higher than 20°C, the opening of the short-circuit solenoid valve is reduced, and the refrigerant flowing into the dehumidification heat exchanger 314 increases until the temperature detected by the third temperature sensor of the dehumidification heat exchanger 314 is lower than 20°C. The dehumidification fan is powered on and runs at low wind speed; then the temperature of the third temperature sensor is detected to be lower than 15°C. If so, the dehumidification fan is shifted up to medium wind speed; if higher than 15°C, the opening of the short-circuit solenoid valve continues to decrease until the temperature detected by the third temperature sensor is lower than 15°C, and the fan is shifted up to medium wind speed; then the temperature of the third temperature sensor is detected to be lower than 10°C. If higher than 10°C, the dehumidification fan continues to run at medium wind speed; if lower than 10°C, the opening of the short-circuit solenoid valve increases, and the amount of refrigerant flowing into the dehumidification heat exchanger 314 decreases, until the temperature detected by the third temperature sensor is higher than 10°C; finally, the system enters a closed-loop feedback, so that when the user presses the <Cooling / Balcony Dehumidification> and <Mid-Gear> buttons again, the temperature detected by the third temperature sensor will be controlled between 10°C and 15°C.

[0169] After pressing <Room Cooling>, the user presses the <Cooling / Balcony Dehumidification> and <Low Gear> buttons, the short-circuit solenoid valve of the balcony dehumidification module will move from the maximum opening state to the initial dehumidification opening state. At this time, the refrigerant liquid condensed by the outdoor unit enters the dehumidification heat exchanger 314 through the throttling of the throttling element for evaporation and heat absorption, so that the temperature of the dehumidification heat exchanger 314 is reduced to realize the dehumidification function. When the temperature detected by the third temperature sensor of the dehumidification heat exchanger 314 is lower than 20°C, the dehumidification fan is powered on and runs at low wind speed. If the temperature detected by the third temperature sensor of the dehumidification heat exchanger 314 is higher than 20°C, the opening of the short-circuit solenoid valve is reduced, and the refrigerant liquid flows into the dehumidification heat exchanger. The refrigerant in the dehumidifier 314 increases until the temperature detected by the third temperature sensor of the dehumidification heat exchanger 314 is lower than 20°C, and the dehumidification fan is powered on and operates at low wind speed; then the temperature of the third temperature sensor is detected to be lower than 15°C. If it is higher than 15°C, the dehumidification fan continues to operate at low wind speed; if it is lower than 15°C, the opening of the short-circuit solenoid valve increases, and the amount of refrigerant flowing into the dehumidification heat exchanger 314 decreases until the temperature detected by the third temperature sensor is higher than 15°C, and the dehumidification fan continues to operate at low wind speed; finally, the system enters a closed-loop feedback, so that when the user presses the <Cooling / Balcony Dehumidification> and <Low Gear> buttons again, the temperature detected by the third temperature sensor will be controlled between 20°C and 15°C.

[0170] When the user presses <Room Heating>, the functions of the balcony dehumidification module and the balcony dryer 312 are swapped. The user can press the <Heating / Balcony Dehumidification> button to dehumidify the balcony, and press the <Heating / Balcony Drying> button to dry the balcony. The control logic is the same as that of the balcony dehumidification and balcony drying during <Room Cooling>.

[0171] In addition, there is a timer switch function. After pressing the <Cooling / Balcony Drying> button, the user presses the <Timed On / Off> button once within 10 seconds, and the balcony dryer 312 is timed on. The duration is controlled by time <+> and <->. After pressing the <Cooling / Balcony Drying> button, the user presses the <Timed On / Off> button twice within 10 seconds, and the balcony dryer 312 is timed off. The duration is controlled by time <+> and <->. The timer switches for other functions are the same as above.
